RE-REPEATING HISTORY: Greg Stein looks at disaster preparedness, disaster responses, and changes in building codes, and observes a cycle of response and relaxation that seems to fit a lot of human affairs. He notes a connection between the Triangle Shirtwaist fire and the World Trade Center collapse, and also has some thoughts on what to do about this phenomenon. Plus, the quick-thinking lifesaving heroics of a law professor and his students. No, really.
